Inference that learns from your work.

Lower costs without compromising quality. One inference endpoint that learns from your traffic and team judgment to continuously optimize prompts, route requests, and train custom models.

For AI-native companies

One endpoint. Continuously optimized.

Ambral continuously tests cheaper models and prompt changes against your production workloads, then trains specialized models where the gains justify it. Every change is evaluated against your quality bar before deployment, with frontier models available for the tasks that need them.

Point your existing client at Ambral. Requests pass through to the model you already use, and every call, tool invocation and outcome is captured as a trace.

Use built-in connectors to bring in context and outcomes from the tools you already use, giving Ambral a fuller picture of what good work looks like.

Ambral turns production traces into evals grounded in your tasks, context, and outcomes. It tests candidate models against that suite and brings uncertain cases to your team for review.

  1. Connect

    Traces become evals

    Real traffic becomes an eval suite. No hand-written test sets, no ML team to start.

  2. Evaluate

    Your team weighs in where it matters

    Ambral asks only on judgment calls. Pick one, add context, and it is remembered.

  3. Optimize

    Smaller models, same quality

    Ambral optimizes prompts and, when it pays, trains smaller models on your work. Traffic switches only when evals show they match frontier quality on your workload.

  4. Learn

    Real outcomes feed back

    Accepted outputs, merged changes and closed deals flow back. The model improves from how that workload went.
